NON-REFILLABLE BOTTLE.

S1EGIFIOATION forming part of Letters Patent No. 757,391, dated April12, 1904.

Application filed August 7, 1903.

To aZZ whom it may concern.-

Be it known that I, WILBUR A. COKE, a citizen of the United States,residing at Norfolk, in the county of Norfolk and State of Virginia,have invented new and useful Improvements in N on-Refillable Bottles, ofwhich the following is a specification.

1 This invention relates to non-refillable bott es.

The object of the invention is whilpermitting free escape of the liquidcontained within the bottle positively to preclude refilling of thesame, thereby preventing the perpetration of fraud by filling the bottlewith a spurious liquor and foist it upon the public as being of the samebrand as that originally contained by thebottle or package.

With these and other objects in view, as will appear as the nature ofthe invention is better understood, the same consists in the novelconstruction and combination of parts of a non-refillable bottle, aswill be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, andin which like characters of reference indicate corresponding parts,there is illustrated one form of embodiment of the invention capable ofcarrying the same into practical operation, it being understood that theelements therein exhib- '.ited may be varied or changed as to shape,

proportion, and exact manner of assemblage without departing from thespirit thereof, and in these drawings Figure 1 is a view in elevation,partly in section, showing the plug and valve seated within the neck ofa bottle. Fig. 2 is a perspective detail view of the plug. Fig. 3 is asectional detail view of a modified form of valve that may be employed,if found necessary or desirable.

Referring to the drawings, 1 designates the neck of an ordinary bottle,which for a purpose that will presently be described has its boretapered throughout the greater portion of its length and terminatesadjacent to the shoulder 2 in a stop 3, provided with a central duct 4,in the upper end of which the valve 5 rests when the bottle occupies anup- Serial No. 168,674. (No model.)

right position. The valve 5 may be of any suitable material, such as anordinary marble, or it may be a rubber sphere, or, as shown in Fig. 3,the center 6 of the valve may be of a solid non-yielding materialinclosed by an elastic sheathing or covering 7, of rubber or any othermaterial constituted to the purpose. The salient feature of the presentinvention resides in the plug 8, (shown in detail in Fig. 3,) the samebeing tapered to fit the bore of the neck and is held therein in anysuitable manner, as,by means of cement or glue, the lower end of theplug when positioned within the bore of the neck resting upon the stop3, as clearly shown in Fig. 1. The reason for making the bore of theneck and the plug on a taper is to insure a tight union between theparts when assembled, thus to prevent removal of the plug for illicitpurposes. The exterior of the plug is. provided with a spiral thread 9,the groove between which forms an escape-duct to permit passage of theliquid from the body outward through the neck. The lower portion of theplug is provided with a chamber 10, which is of such depth that when thebottle is inverted for the purpose of pouring out the contained liquidthe valve will be entirely housed within the chamber, and thus permitthe liquid to pass from the duct 4 around the grooves of the plug andthence outward. One side of the lower end of the plug is provided with arecess 11, the object of which is to permit free egress of the liquid.

So long as the bottle remains in an upright position or is even slightlytilted escape of liquid is positively prevented; but as soon as thebottle is practically inverted the liquid will pass from the duct 4around the groove of the plug and thence outward. If an attempt be madeto refill the bottle after having been emptied, the valve 5 willpositively preclude this, as it will always rest upon the seat formed inthe upper end of the duct, and thus not only seal the bottle fromentrance of liquor from without, but also from the escape of air fromwithin, so that liquid could not be supplied to the bottle.

While the device of this invention is exceedingly simple inconstruction, it will be found thoroughly efficient in use and will in apositive manner perform the functions designed.

Having thus described the invention, what I claim is 1. A bottle havinga neck, a stop in the neck, and a duct connecting the interior of theneck and the body of the bottle, combined with a plug permanentlysecured in said neck and fitting against said stop, the plug beingexternally threaded, having a chamber in its lower side and a recessaffording communication between said chamber and the lower end of thegroove between the threads of the plug, and a valve adapted, when thebottle is in an upright position, to be seated against the upper end ofsaid duct, and when said bottle is tilted or inverted, to enter saidchamber.

2. A bottle having a neck, an annular stop in the neck, and a ductconnecting the interior of the neck with the body of the bottle,combined with a tapered plug permanently secured in said neck, thelatter being also tapered interiorly, said plug fitting against saidannular stop, being externally threaded, having a chamber in its lowerside, and an aperture affording communication between said chamber andthe lower end of the groove between the threads of the plug, and aspherical valve adapted normally to be seated against the upper end ofsaid duct and to roll in said chamber when the bottle is tilted orinverted.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

WILBUR A. COKE.
